True Faith Gives Full Assent to the Scriptures

We having the same spirit of faith, according as it is written, I believed, and therefore have I spoken; we also believe, and therefore speak; _ 2 Corinthians 4:13

I may know a thing, and yet not believe it. Therefore assent must go with faith: that is to say, what we know we must also agree unto, as being most certainly the verity of God. Now, in order to faith it is necessary that I should not only read the Scriptures and understand them, but that I should receive them in my soul as being the very truth of the living God, and I should devoutly with my whole heart receive the whole of the Scripture as being inspired of the Most High, and the whole of the doctrine which He requires me to believe to my salvation. You are not allowed to halve the Scriptures, and to believe what you please; you are not allowed to believe the Scripture with a half-heartedness, for if you do this wilfully, you have not the faith which looks alone to Christ. True faith gives its full assent to the Scriptures; it takes a page and says, “No matter what is in the page, I believe it;” it turns over the next chapter and says, “Herein are some things hard to be understood, which they that are unlearned and unstable do wrest, as they do also the other Scriptures, to their destruction; but hard though it be, I believe it.” It sees the Trinity; it cannot understand the Trinity in Unity, but it believes it. It sees an atoning sacrifice; there is something difficult in the thought, but it believes it; and whatever it be which it sees in revelation, it devoutly puts its lips to the book, and says, “I love it all; I give my full, free and hearty assent to every word of it, whether it be the threatening or the promise, the proverb, the precept, or the blessing. I believe that since it is all the Word of God it is all most assuredly true.” Whosoever would be saved must know the Scriptures, and must give full assent unto them.~ C.H. Spurgeon
